Question 1.
What does Ku represent in the Ziegler-Nichols method?
Show hintHide hint
Think about what happens to the system when it oscillates stably.
Question 2.
State the formula for Kp in the Ziegler-Nichols method.
Show hintHide hint
What do we multiply the critical gain by?
3Question 3.
What is the purpose of the Ziegler-Nichols method?
- To stabilize the PID controller
- To tune PID parameters
- To measure system output
Show hintHide hint
Remember the main objective of this method.
4Question 4.
True or False: The integral gain (Ki) is set to zero at the start of the Ziegler-Nichols method.
- True
- False
Show hintHide hint
Recall the initial setup of the method.
Question 5.
A certain control system shows sustained oscillations with Ku = 25 and Pu = 4 seconds. Calculate the PID parameters and discuss any limitations of using these parameters.
Show hintHide hint
Use the formulas carefully and think about system behavior.
Question 6.
Describe how you would approach tuning a PID controller in a real-world scenario where the Ziegler-Nichols method yields oscillations that are too pronounced.
Show hintHide hint
Consider what adjustments can stabilize the output.
